Whatever the case may be, you sometimes may wonder how to extract the sound from the MP4 and convert it to a MP3 audio file on Mac /PC, so that you then can listen to the music on a MP3 audio player.
What is MP4 (mpeg-4, h.264) video format
MP4 (MPEG-4 Part 14) is a digital format standard for storing video and audio, as well as data such as subtitles and still images. It can hold high-quality, highly compressed digital video encoded by mpeg-4 or h.264, along with AAC, MP3 or AC3 audio. MP4 is popular on the Internet and supported by a list of different devices.
